CHARLES W. NEWTON, OF BOSTON', MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO UNTED SHOE MACHINERY CGRPORATON, OF PATERSON, NEW JERSEY,

A CQBPOBATION OF NEV JERSEY.

FOLDING Application filed March 20, 1920, Serial rlhis invention relates to machines for finishing the edge of a piece of sheet material and is herein illustrated as embodied in a machine designed to produce so-called French edges on parts of uppers of boots and shoes and to perform similar operations.

lt is customary in the manufacture of certain styles of boots and shoes to bind the edges of parts of the uppers with a stripof fabric. To this end such a strip is stitched to the edge of a vamp, quarter or other part which is to be bound, cement is applied to the strip after which the free portieri of the strip is folded about the edge of the vamp, quarter or other piece and pressed down so that the cement may hold it firmly in place.

DurinT the folding operation, it is desirable to pull or wipe the free portion of the binding over that portion of itself which is attached to the material so that there may be nov looseness or Wrinkles in the finished edge, this being true whether or not the binding has been previously pulled out. To this end, the binding-engaging member of the illustrative machine which operates upon the under side of the work (or upon that side of the material to which the binding is attached) is a narrow member of rigid material which is caused to move intermittently in a direction to pull the free portion of the binding over the attached portion thereof.

After the binding has been thus pulled out, it is drawn over the edge of the material. In the illustrated machine, this drawing over or folding operation is performed by a second binding-engaging member which is also rigid and narrow, the two members being lo-v cated substantially one above the other. By providing members of this kind which coopcrate to pull out. and fold the binding, the resultant edge is compact and uniform in appearance, and curved edges may readily be operated upon.

'llhcse and other features of the invention, including certain details of construction and col'nbinations of parts, will be described as embodied in an illustrative machine and pointed out in the appended claims.

Referring now to the accompanying drawings,- p

Fig. 6 is a section through the same piece of work after the free portion of the binding has been pulled out or straightened, and

Fig. 7 is a section through the same piece of work after it has been operated upon to form a French edge.

Referring first to Figs. 5, 6, and 7, in the formation of a French edge a binding strip 201, usually fabric, is fastened to a part of the upper 203 of a shoe, which is usually leather, by stitches 205. The next operation is to pull out or straighten the binding, as shown in Fig. 6, which may be done by hand or by the use of a machine such as that shown in the patent to Mcntire No. 1,322,591. The Work in substantially this condition and with a coat of cement applied to the upper side of the binding is then fed to a machine which folds the free portion of the binding about its attached portion and about the edge of the upper material to produce the effectshown in Fig. 7. lt has been stated above that after the binding has been pulled out either by hand o-r by machine, it presents substantially the appearance shown in Figure 6. It should be understood, however, that although the free portion ot the binding may be pulled out to the position shown, it will seldom remain exactly in that position, particularly if the preliminary pulling out has been done by hand. There will thus always be some looseness in the locality in which the free portion of the binding extends over the attached portion; and this looseness should be talen up completely in the subsequent operations upon the work. It is one object of the present invention to taire up this lcoseness, whether or not the binding has been previously pulled out, by exerting a pull upon the binding during the operation of the machine of the present invention, and particularly to provide means for drawing the free portion of the binding aboutthe attached portion and about the edge of the material when sharply curved edges are encountered.

Although the work has thus far been referred to as having a French edge formed upon it, the machine of the present invention is equally well adapted to fold a binding or anything which has the characteristics of a binding over the edge of a piece of material. In this connection it should be noted that the work shown in Figs. 2 and 3 comprises a blank of buckram 301 or other comparatively stiff material one side and the edge of which is covered by a piece of thin leather 303 or other' comparatively flexible material., the machine of the present. invention being adapted to fold th'e projecting margin of the leather over the edge of the buckram.

Before proceeding` to a detailed cescription of the construction of the machine, a brief description of its general mode of operation will be given. rlhe margin of the work is fed intermittently over a support 9 by the cooperative movement of an upper feed member 11 and a lower feed member 13, and is guided in such movement by an edge gage 15. The surface of the more flexible component of the work is in contact with the gage, but it is the edge of the less flexible material which determines, in vconjunction with the guiding by the operator, the general path of the feed. The feed mechanism operates intermittently upon the work; and during the pauses in the feed a presser-foot 17 holds the work upon the support, said foot having formed on its lower end a thin, flat horizontally extending portion 117 which serves as a creaser or fold guide. rllhe combined foot and creaser is shown in this position in Fig. 3. At this time a folder or wiper' 19, hereinafter referred to as the upper wiper or binding-engaging member, is actuated to push the upstanding margin of the more flexible material over the creaser 117. At the same time that the upper wiper 19 is operating as has just been described to push the upstanding margin of the more flexible material to the left, a second wiper 21 (sce Fig. 2), hereinafter referred to as the under Wiper or binding-engaging member, is moved to the right in such manner as to co-operate with the upper wiper in drawing the more flexible material tightly about the edge of the less flexible material. The presser' foot 17 then rises slightly and the wipers are moved away from the work and respectively to the right and to the left so as to be in positions to repeat their co-operating folding movements as soon the work has been fed forward another step. The feed mechanism now advances the work one step, and thereafter the presser-foot 17 descends again, and the Wipers 19, 21 again make their operative movements. lt is desirable, of course, that, after the wipers have operated to form the fold, and the folded margin has been fed past the creaser 117, the fold should be pressed. To this end the upper feed member 11 has fast to it a fold presser or hammer 23 which descends with the descent of the upper feed member and presses or hammers the fold against the work support. In this Way the portion of the more flexible material which projects beyond the edge of the less flexible material is progressively folded over'and hammered down upon the upper margin of the less flexible material. With this brief description of the general mode of operation of the machine, a detailed description of its construction will now be given.

Referring more particularly to Figs. 1 and 2, the illustrative machine was Vmade from an old and well-known type of sewing machine, the frame and feed mechanism. remaining unchanged except as pointed out below, the needle-bar and shuttle having been removed. The frame comprises a work-supporting arm 25 and an overhanging arm 27, there being mounted in the overhanginv' arm a drive shaft 29 and in the Work-supporting arm a counter-shaft 31 which is driven from the drive shaft by double cranks on the respective shafts and connecting links 33. Also mounted in the work-supporting arm a rock shaft 35 which is oscillated by the drive shaftthrough an eccentric 37, a connecting link 39 and an arm 41. Fast to the outer end of the counter shaft 31 is an eccentric 43 encircling which is an eccentric strap to lower feed member 13 a Well-known Inove-V ment the path of which is in general ellipti-` cal. rlhe effect is to canse the member 13 to rise into Contact with the under side of the work, to feed the work one step and then descend and return to its first position.

Turning new to the upper feed-member 11 and pressenfoot 17, these parts are operated in the following manner: The presserfeot 17 is fast to an upright rod 53, which is vertically slidable in alined bearings formed in the overhanging arm 27, said rod being urged downwardly at all times by a comparatively heavy spring which bears at its upper end against the arm and at its lower end against a collar 57 adjustably CTI fastened to the rod by a-pinch-screw 59. v A bracket integral with the collar carries a pivot (not shown) upon which is mounted the hub of a bell-crank lever having a. subst-antially vert-ical arm 61 and a substantially horizontal arm 63, said hub being held 'in place' on t-he pivot by a screw 65 which is threaded into one end of the pivot. The horizont-al arm 63 is pivoted at its outer end at 67 to the upper end of a rectangular rod 69 to the lower end of which the upper feedmember 11 is adjustably fastened by a screw 71. The arm 69 is permitted a certain amount of swinging -movement about the pivot 67 and passes through what amounts to a slot in a portion of the overhanging arm 27. Three sides of the slot are formed by the walls of arecess 73 cut in the arm 27 and the fourth side is formed by a lug 7 5 which is fa st to or part of said overhanging arm. A leaf spring 77, attached at its upper end to the rod 69, bears against the forward or left-hand wall of the recess 73 and tends at all times to swing the rod 69 into contact with the rear or right-hand wall of the recess, as shown. The upright arm 61 of the bell crank lever referred to above is pivoted at 79 to one end of a link 81 the other end of which is pivoted at 83 to a crank arm which is rigid with a disk 87 on the outer end of the drive shaft 29.

The operation of the feed mechanism is briefiy as follows: Assuming that the disk 87 is rotating in the direction indicated by the arrow and that the pressure-foot 17' is restingr upon the work so that no further downward movement of the rod 53 is possible, the effect of moving the pivot 83, the link 81 and consequently the upright arm 61 to the left will be to raise the rod 69 and consequently the upper feed-member 11, the raising taking place about the pivot which at this time acts as a fixed pivot. As soon, however, as the upright arm 61 has passed its extreme left-hand position and begins to return, the rod 69 and feed-member 11 will be lowered until the downward movement of the feed-member is arrested by contact with the work. As soon as this happens, the pivot 67 will act as a iXed pivot, and the pivot 65, together .with the rod 53, will begin to rise against the force of the spring 55. This will continue until t-he upright arm 61 passes the `limit, of its righthand movement and begins its movement to the left again. During this left-hand movement, the rod and pivot 65 will be lowered until the presser-foot 17 again contacts with the work, whereupon the rod 69 and feed member 11 will be raised again, this cycle of movement-s continuing as long as the shaft 29 rotates. The movements of the various parts of the machine are so timed that the lower feed-member 13 rises to force the work against the lower face of the upper feed member 11 just as the presser-foot 17 is being raised from the work. The lower feed-member isv then moved forward therebyv and presser-foot simultaneously, for eX-` ample to facilitate removal ofa piece of work from the machine, a finger piece 89 may be manipulated. The details of the feed mechanism which has thus been described form no part per se ofthe present invention, and any suitable feed mechanism may be used.

Referring now more particularly to Figs. 2, 3 and t, the construction of the wipers 19 and 21 and their operating mechanism will. be described. The upper wiper 19 is fastened to a strip of spring steel 91 by a screw 93 which passes vthrough a block 95 and is threaded into the spring strip, the strip in turn being fastened by a screw 97 to a slide 99 mounted in a suitable guideway on the work-supporting arm 25. The slide is pivoted at 101 to one end of a link 103 the other end of which is pivoted at 105 to an arm 107 formed on the upper end of a vertical rockshaft 109, said rock-shaft being angularly movable in a vertical bearing 111 carried by the frame of the machine. The wiper or folder is thus moved over the end of the creaser or fold guide 117 in a path which is substantially parallel to the plane of the workg and the height of the folder may be changed as desired to provide for pieces of work of different thicknesses by turning the screw 127. To the lower end of the vertical rock-shaft is fastened a hub 113 having integral therewith an arm 115. A screw 119, threaded through the arm, is connected by a spring 121 with the frame of the machine and carries a roll 123 which co-operates with a cam 125 fast to the counter-shaft 3l.

In order to hold the upper wiper 19 more securely a block 126 is held against its rear end by a screw 128. From this construction it will be evident that rotation of the counter-shaft will cause reciprocation of the slide 99 and with it of the upper wiper 19. With the parts in the positions shown in Fig. 2, the wiper 19 is in its eXtreme righthand position. Presently it will be moved to the left to lay the margin of the more flexible material 303 over the edgeof. the less flexible material 30.1. If it were permitted to return to the right in the same path in which it moved to the left, Vit would tend, particularly by reason of the teeth on its lower face, to pull back the margin of the v 91, said pin being vertically slidable in a bore 130 in a stationary block 131 and resting at its lower end upon a cam 133 fast to the lshaft 31. Rotation of the shaft 31,

therefore, causes the upper wiper 19 to be moved first to the left to fold the work, then to be raised and retracted and then to be lowered into the positionshown. In order to add to the strength of the spring strip 91, a leaf spring 135 is fastened to it by the same screw 97 which fastens the strip to the slide 99. And in order to compel the wiper 19 to be raised whenever the finger piece 89 is manipulated to raise the presser-foot 17, the block 95 has an outwardly extending arm which overlies a finger 137, said being fastened to the presser-foot by a screw 139.

r1`he under wiper 21 is fast to a box yoke 14:1 which is mounted on the station ary block 131 so as to permit its front and side portion to be movable both angularly and bodily with respect to the block. To this end the yoke embraces the upper squared portion of the block, the rear bar 14:5 of the yoke being received-in a guideway 147 formed between projecting ears 149 on the block and being pivoted at its ents at 151, 153 to the side bars or arms of the yoke. The yoke is moved to the right (see Fig. 2) by the rising of a push-pin 155 in a bore 15G, the upper beveled end of the pin co-operating with the beveled end of a projection 157 on the rear bar 14.5 of the yoke. A spring 159 extending into a socket in Jthe work-supporting arm of the machine tends at all times to move the yoke, and with it the wiper 21, to the left. The push-pin 155 is raised at the proper time by a cam 161 on the counter-shaft 31. r1`he combined action of the push-pin 155 and the spring 159 thus serves to move the wiper 21 first to the left and then to the right. ln its movement to the right, the wiper should Contact with the work and thereby aid the wiper 19 (which at that time is moving to the left) to form a tight fold. lin its return movement (to the left) it should be out of contact with the work. To this end it is raised and lowered at the proper times about the axis of the pivot 151 by a third pushpin 163 which is vertically slidable in a bore 165 in the block 131, said pin having an arm 157 the upper face of which cont-acts with the head of a small screw 169. This screw is loose in a socket in the front bar of the yoke 141 and does not serve the ordinary purpose of a screw. It is in reality merely a contact member, and carries a coiled spring 171 so that the under wiper 21 is raised yieldingly when the push-pin 163 is raised. f

Referring again to the upper feed-member 11 and to the presser-foot 17, the feed-member has fast to or integral with it the hammer or fold presser 23 which operates to press or hammer the folded margin of the binding or similar member down upon the margin of the body material; and the pres ser-foot has the thin horizontal extension 117 which serves as a creaser over which the margin of the binding is folded. In this connection it should be noted that the eX- tent to which the presser-foot 17 is raised is slight as compared with that of the upper feed member 11 and hammer 23. rflue general mode of operation of the machine has been described above. 1n particular it should now be noted that the binding-engaging members 19, 21 are made of rigid material, are comparatively narrow and execute their operative movements during the pauses in the intermittent feed movements. TWith such a construction and mode of operation the drawing` of the binding about the edge to be bound is thorough so that wrinkles or bunches which have tended to occur with prior machines are obviated, and the folding of convex curves, particularly of abrupt curves commonly known as corners which occur for example in button flies and in the small reinforcing article shown in Figs. 2 and 3, is greatly facilitated. As has been explained, the machine is adapted to fold a strip of binding, such as that shown at 201 in Figs. 5, 6 and 7 or a piece of covering material such as that shown at 303 in Fig. 3 or to perform similar operations. 1n order to promote brevity the work, throughout the claims, will be referred to as a piece of material to which a piece of binding is attached.
